“…This method of solution is typical for similar more complex cases of loading of multibolt connections, either for assembly or operating conditions [8,9]. An example of how the finite element method can be useful in improving or replacing existing calculation methods of a bolted connection of an end-plate cantilever beam can be found, for example, in [10].…”

“…A key source of information is the book by F. Pospisil [7], which is still one of the most detailed summaries of knowledge about bolted connections based on experiments and practical experience. Numerical calculation methods (FEM), as an alternative to existing theoretical approaches, have also been studied further in [8][9][10]. It has also proved very appropriate to combine the numerical approach with the experimental one as did T. Benhaddou [11].…”

This article discusses the issue of force behavior in a pre-tensioned bolt that is part of a symmetrical flange connection, loaded with an operating load parallel to the bolt axis. The first part describes the issue being dealt with in detail. The next part offers a brief description of the generally known theoretical approach to the solution, and also outlines the limitations of this approach. This part is followed by a theoretical analysis of working load behavior in the bolt of the analyzed device, using Finite Element Method (FEM). In this article, a comparison of several different approaches to the solution can be also found, followed by a description of the experiment preparation and its results. The obtained values also serve as a subject for reverse iterative analysis carried out using ANSYS software. The aim is to find a proper modification to the symmetric calculation model that would be consistent with the results of measurements from technical practice. All results achieved are described in the final part of the article.

This article deals with the uniformity of the distribution of axial forces between the individual bolts of the clamping sleeve. Clamping sleeves are machine components connecting the shaft to the hub using contact force. For sleeve pretension, bolts are used and positioned symmetrically with respect to the axis of the clamping sleeve. Though the bolts are placed symmetrically around the axis, the bolt axial forces are not uniformly distributed when the bolts are tightened according to the manufacturer’s catalog. First, this article describes the procedure for tightening the sleeve bolts according to the manufacturer’s catalog. In the next part of the article, an FEA simulation of sleeve tightening is performed. The FEM simulation is then compared with the values found by measurement.

“…It was discovered that the tension was distributed more uniformly in joints with more rigid gaskets. Many papers have investigated the impact of various contact issues on the accuracy of the numerical solution [9][10][11]. Moreover, studies [12,13] analysed the influence of the rigidity of a gasket on the bolts' tension level caused by the increase in pressure of the sealed medium.…”

The paper presents the proposal of a leakage prediction method in flange joints, after pipeline deformation, based on FEM (Finite Element Methods). The stages of developing the design are discussed, and a complex, multi-stage method of applying the loads is presented in detail. Moreover, the gasket material data obtained in experiments were used. The paper also presents the results of calculations on a non-uniform stress distribution in the radial direction of the gasket. In addition, it has been shown that the deflection of the pipeline with a minor displacement causes an increase in the diversification of the circumferential pressure of the gasket, and also has a significant influence on the determination of the actual state of stress to which the gasket is subject. Moreover, it was found that the distribution of contact pressure on the deflection of the pipeline has a significant influence on the level of leakage. The results of tests are compared to the results of the numerical calculations of the stress in bolts. By comparing the bolt tension changes obtained by numerical and experiment analyses, it has been shown that the assumptions made in developing the numerical model are correct.
